Here\'s my environment:
➜ AwesomeProject node --version v6.3.0 ➜ AwesomeProject npm --version 3.10.3 ➜ AwesomeProject react-native --version react-native-cli: 1.0.
I ran into this problem when I ran react-native run-ios within the terminal multiplexer tmux. I fixed it by running react-native run-ios in a normal terminal tab without tmux running.
react-native run-ios
tmux
